For the past couple years, Cooler Master has run an annual Case modding competition which has produced some of the most stunning examples of both professional and amateur PC builds from around the globe. Well... It's that time of the year once again! Starting today, the CoolerMaster Case Mod 2013 Competition is featuring two categories: scratch builds and tower mods. Therefore, whether you have an exciting idea about a scratch build, or you already own a case that could use some "fine-tuning", you should definitely give your modding skills a run for their money.
